You might want to replace your model with waifu diffusion.
1) Download the waifu diffusion model here: https://github.com/harubaru/waifu-diffusion/blob/main/docs/en/weights/danbooru-7...
2) Open folder aiimages_standalone\stable-diffusion\models\ldm\stable-diffusion-v1
3) Rename your old model file to "model_original"
4) Copy the downloaded waifu diffusion model there and call it "model"
5) Run aiimag.es
There is also something called "embeddings", where you can teach the AI new words (needs 5 images of the word and 1h on a RTX 3090ti). I might add a UI for that later or - if you are really really tech savvy - you can run it via the "stable-diffusion" folder in a command line. https://github.com/invoke-ai/InvokeAI/blob/main/docs/features/TEXTUAL_INVERSION....
